Biomass pyramids show the amount of organic material at each trophic level; thus, they are the best type of ecological pyramid to use in order to model the flow of matter through an ecosystem. A numbers pyramid would not as accurately display this kind of information because a larger producer, such as a tree, which contains a great deal of matter, would be able to feed hundreds or thousands of small first-level consumers such as wood-eating insects.

<span>The water molecule, as a whole, has 10 protons and 10 electrons, so it is neutral.In a water molecule, the oxygen atom and hydrogen atoms share electrons in covalent bonds, but the sharing is not equal.In the covalent bond between oxygen and hydrogen, the oxygen atom attracts electrons a bit more strongly than the hydrogen atoms.The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.<span>Water molecules attract one another based on the attraction between the positive end of one water molecule and the negative end of another.</span></span>
False, that is one thing many people were always doing, back then.
Answer:
Explanation:
Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
